Effect of cold isostatic pressing and VC grain growth inhibitor addition on WC grain size and mechanical properties of WC-8Co cemented carbide / Gennadiy Akimov ... [et al.]

In this study, sub-micron WC-Co cemented carbides were fabricated by cold isostatic pressing using recycled WC powder, Co powder, and VC grain growth inhibitor as the initial composite powders. The raw WC-8Co and WC-8Co-0.3VC compositions were prepared according to conventional technology. After tha...
